Mechanical Design Engineer

Location: Durham

Contract Type: Permanent / Full Time

Closing Date: Sep 18th, 2026

Ref: 1677826

Wolviston Management Services is delighted to be working with our amazing client to recruit a Mechanical Design Engineer to join their established engineering team.

This is an excellent opportunity to contribute to the design and supporting programmes from initial concept through to full-scale production across telecoms, aerospace, defence and space sectors.

The Role As a Mechanical Design Engineer, you will provide end-to-end engineering support across, modules and amplifiers. The role demands a strong focus on mechanical integrity, thermal performance, reliability and manufacturability within high-specification environments.

You will play a key role in delivering robust, lightweight and thermally efficient designs suitable for demanding industrial and high-reliability applications.

Key Responsibilities Mechanical Design & Development

• Design precision components and assemblies including enclosures, heatsinks, liquid-cooled systems and waveguide structures


• Develop modular architectures for integration into larger system-level assemblies


• Ensure compliance with RF, thermal, environmental and mechanical performance requirements


• Produce detailed 3D CAD models and engineering drawings (SolidWorks)


• Define materials, finishes and manufacturing processes aligned to performance and cost targets

Analysis & Validation

• Undertake thermal analysis including CFD to validate cooling strategies


• Perform structural and dynamic analysis (FEA) covering vibration, shock and fatigue


• Validate analytical models through testing and data correlation

RF-Aware Engineering

• Collaborate with RF and electronics teams to optimise mechanical impact on RF performance


• Support design of waveguides, precision features and PCB-integrated assemblies


• Contribute to electromechanical concept development

Manufacturing & Delivery

• Design for manufacture, assembly and cost efficiency across CNC machining, casting, additive and sheet metal processes


• Produce engineering documentation including BOMs, GD&T drawings and assembly instructions


• Support prototype builds, first article inspection and production introduction


• Participate in design reviews and change control processes (ECN/ECO)

Prototyping & Testing

• Support build and validation of development hardware


• Assist with environmental and reliability testing (thermal, vibration, humidity, shock)


• Contribute to development of production tooling, jigs and fixtures

Requirements Essential

• Degree (or equivalent) in Mechanical Engineering


• Strong 2D/3D CAD capability (SolidWorks preferred)


• Experience designing high-precision assemblies in demanding environments


• Knowledge of PCB integration, RF shielding and EMI/EMC considerations


• Good understanding of materials, manufacturing processes and GD&T


• Experience producing detailed engineering drawings


• Strong team collaboration and stakeholder engagement skills

Desirable

• Experience in aerospace, defence, telecoms or space-related programmes


• Familiarity with RF/mmWave systems and high-frequency product design


• Experience with FEA and thermal simulation (e.g. SolidWorks Simulation/Flow)


• Knowledge of lightweighting and structural optimisation techniques


• Exposure to high-reliability standards (MIL-STD, ECSS)


• Experience with environmental testing and qualification processes


• Understanding of RoHS/WEEE compliance

Personal Attributes

• Strong analytical and problem-solving capability


• Detail-oriented with a proactive, hands-on approach


• Able to manage multiple priorities and deliver to deadlines


• Effective communicator across multidisciplinary teams and stakeholders


• Self-motivated and committed to continuous development
